Live coverage: India’s first space observatory in orbit

SpaceX’s Falcon Heavy rocket lifted off from NASA’s Kennedy Space Center in Florida at 2:30 a.m. EDT (0630 GMT) to begin a three-and-a-half hour mission to deliver two dozen satellites into three distinct orbits. The Falcon Heavy’s two side boosters returned to Cape Canaveral for successful landings, but the center core stage crashed during a landing attempt on SpaceX’s drone ship in the Atlantic Ocean.

NASA has selected three finalists for a new Explorer-class astrophysics satellite mission scheduled to launch by the end of 2020, and two of the proposals aim to fulfill similar goals to an X-ray telescope shelved after cost overruns in 2012.

Rocket Lab’s second Electron booster lifted off from New Zealand’s North Island on Saturday, U.S. time, and reached orbit after an eight-minute climb over the Pacific Ocean. Liftoff with three commercial CubeSats occurred at 8:43 p.m. EST Saturday (0143 GMT; 2:43 p.m. New Zealand time Sunday).
